(November 12, 2007 - Insidermedicine) From Boston - Beta-carotene may lower the risk of cognitive decline. In a clinical trial of over 4000 subjects followed for nearly 2 decades, those randomized to 50 mg of beta-carotene every other day did better on cognitive tests compared to those who took placebo. Protective effects were not seen in the short-term.

From Alabama - Refractive errors are common in nursing homes and correcting them with appropriate glass power can have significant benefits. A study of nearly 150 nursing home residents showed that getting appropriate glass power shortly after an eye assessment not only improved vision and ability to participate in hobbies, but lowered the prevalence of depressive symptoms.

Back to Boston - Exercise may help women with fibromyalgia. In a study of over 200 women, those randomized to receive both exercise and education or exercise alone experienced a benefit in physical and emotional well being. Simple activities like walking, stretching and strength training are recommended.

And finally from Norway - There is further evidence that omega-3 fatty acids might prevent cognitive decline. In a cross-sectional study of over 2000 subjects, those who ate more than 10 grams of seafood per day did much better on tests measuring cognitive ability compared to those who ate less.
